COMPENSATING HUB FOR LOCKS OR LATCHES.

SPECIFICATION forming part of Letters Patent No. 765,909, dated July 26,1904.

Application filed May 6, 1904. Serial No. 206,605. (No model.)

T 0 all whom it may concern:

Be it known that I, HENRY G. VOIGHT, a citizen of the United States,residing at New Britain, in the county of Hartford, State ofConnecticut, have invented certain new and useful Improvements inCompensating Hubs for Looks or Latches, of which the following is afull, clear, and exact description.

Hy invention relates to locks and latches, and particularly to the hub.

My object is to provide in a lock or latch case a hub which mayoscillate after the usual manner and which may be rocked or swung out ofa line diametrical to the lock-case to a sufiicient extent to preventcramping or binding of the parts in use. I/Vhen an ordinary mortise-lockis applied to adoor, the lock-case is set into a mortise so arrangedthat the faceplate will lie flush with the edge of the door. Since somedoors are provided with beveled edges, sometimes lock-cases arenecessarily introduced in a plane oblique to the outer and inner surfacethereof. In all cases, however, knob-spindles are passed through thedoor at right angles thereto, and consequently unless some loose play isprovided when the knobspindle is turned it is liable to produce abinding or cramping of the parts, impairing the free action of the lock.

The purpose of my invention, broadly, is to provide in a simple mannercompensating means to avoid any possible undue cramping or binding.

In the drawings, Figure 1 is a conventional representation of a latchand part of a latchcase, showing the hub in place. Fig. 2 is a plan viewof the hub, showing adjacent parts in section. Fig. 3 is a sideelevation of the hub detached. Fig. 4c is a rear elevation of the hub.Fig. 5 is a front elevation of one of the bearings for the hub. Fig. 6is a perspective view thereof.

1 is a portion of a lock-case.

2 is a latch.

3 is a latch-slide.

4 I are roll-back arms cooperating with the latch-slide.

5 is a hub carrying said roll-backs, the ends of said hub being roundedor I semispherical.

6 is a spindle-passage extending transversely through the hub 5 from endto 'end.

6 is a spindle. The roll-backs 4 4 are pref erably formed integral withthehub 5.

The lock-case 1 is equipped with suitable hub supports or bearings 7 7for the rounded ends of the hub 5. These bearings are annular and arecupped or rounded out, as at 7. The bearings or supports 7 7 arepreferably formed separately from the lock-case, but may be formedintegrally therewith. When formed separately, these bearings 7 havereduced shank portions 7 b arranged to fit freely within the aperturesin thelock-case. This arrangement is best seen in Fig. 2, and the dottedlines will indicate that the spindle may cooperate with the hub eventhough the same is connected therewith in such a manner as to stand atan oblique angle to the lockcase. Were no compensating means provided,if the spindle stood at the angle indicated in dotted lines it isapparent that the rotation of the spindle would produce a wedging orcamming action on the roll-back or associated parts (even if it werepossible to swing said spindle as far out of line as shown) and thefreedom of action of the lock would be greatly impaired;

The bearings 7 when made separately from the lock-case may have freerotative movement therein. Since the hub itself is rotatably independentof the bearings 7, the utmost freedom of action and ease of operation isinsured whether the spindle passes through the lock-case at right anglesor at an oblique angle.

By the term oscillate as used in the fol lowing claims I refer to theusual motion which is given to a lock-hub by the turning of the spindleto draw the latch. By the term rock or rocking I refer to that capacityof the hub to swingso that a spindle which is passed obliquely throughthe lock may cooperate with the hub in such manner as to be entirelyfree.

What I claim is 1. In a lock, an actuating-hub mounted to oscillate andto rock relatively to the lockcase, supports for the hub carried by saidcase and arranged to admit of said oscillating and rocking motion.

2. In a lock, an actuating-hub mounted to oscillate and to rockrelatively to the lockcase, supports for the hub carried by said caseand arranged to admit of said oscillating and rocking motion,and aspindle-passage through said hub transversely of the lock-case.

3. In a lock, an actuating-hub mounted to oscillate and to rockrelatively to the lockcase, rotatable supports for the hub detachablycarried by the lock-case and arranged to admit of oscillating androcking motion of the hub relatively to said case as well as to saidsupports.

4. Ina lock, a lock-case, an actuating-hub, supports on the inner sideof said case to receive said hub and arranged to admit of an independentoscillating and rocking movement of said hub relatively to the lock-caseand an arm projecting laterally of said hub.

5. In a look, a lock-case, an actuating-hub,

supports on the inner side of said case to receive said hub and arrangedto admit of an independent oscillating and rocking movement of said hubrelatively to the lock-case and roll-back arms projecting laterally ofsaid hub and a spindle-passage through said hub at right angles to theplane of the roll-back arm.

6. In a lock, an actuating-hub having rounded ends, a roll-back armcarried by said hub between said rounded ends and a spindle-passagethrough said hub from end to end.

7. In a lock, an actuating-hub, the ends of said hub being rounded, tworoll-back arms carried by said hub and oppositely extending therefromand arranged between said ends, and a spindle-passage extending throughsaid hub from end to end.

8. In a look, a lock-case, an actuating-hub member arranged to berotatably supported within said case, two independent cup-shapedhub-bearings carried by said case said hub having an oscillating androcking movement relatively to said bearings.

9. In a lock, a latch, an actuating-hub adapted to be mounted tooscillate and. rock relatively to the lock-case, substantially asdescribed.
